RADIUS SERVER - IT’S HISTORY AND FUTURE

-

Remote Authentication Dial-In User Service ( RADIUS Server ) is an authentication system that works on the protocol of remote users. It is a client-based networking server that runs on the basis of application layers. Its prime function is to build a core connection of user identities working on a network platform so that no outsider can intrude on the server. The main purpose of RADIUS Server is to determine whether a user can get access to a remote server on the basis of their identity, cause permission to enter the network portfolio is only allowed to the unregistered identities and users.


RADIUS protocol uses RADIUS Server and RADIUS Client for its function. RADIUS Client is more like a networking device that is used for authentication whereas RADIUS Server is a background process that runs on the network.


A RADIUS Server has a lot of components, which ultimately build up the structure of the security system, and its components are as follows -


  1. Supplicant: It is actually an installed software inside the network system,  which passes the information to NAS about the user trying to enter the system.


  1. NAS: It actually works as the client in a client/server architecture.


  1. Server: This is the main functioning body of the whole security system and it waits for the requests from the NAS, so as to verify them.





HISTORY

RADIUS Server was developed by Livingston Enterprises in the year 1991. The running protocol of RADIUS is based on AAA (Authentication, Authorization, Accounting). After it was introduced, the team was contacted by Merit Networks and was even awarded by them for discovering the system.


Later Merit Networks started installing “Portmaster”, which allowed the users to authenticate the servers with dial-in. As soon as the RADIUS Server system was introduced, NAS vendors started purchasing them. And since then people still use it and it is yet one of the best security systems. 


FUTURE

At this point in time, installing RADIUS is easy but if one has to set it up on their own it is indeed a hard task and only the ones with technical knowledge can do it. And if you don’t acquire it then you can go for Hosting RADIUS solution.

This solution provides you with a setup RADIUS Server and often they are known by many names. Also, the perks of it are that they are cost-effective and help the user to utilize the security benefits of RADIUS Servers.

Secure Your Data From Hacker With RBAC System

-
The role based access control system is a secure security approach that helps to protect your business sensitive data from cyber hackers. It is an authorized and restricted cyber security system that gives access data to users that is based on their roles within an organization. It is based on the concept of roles and privileges. The data using the access system is dependent upon authority, competency, and responsibilities.

Security of Zero Trust Model in Business Infrastructure

-
The Zero Trust Mode l is a cybersecurity approach that assumes no trust by default, both inside and outside a corporate network. This means that every user, device, and application trying to access resources on a private network must be verified and authenticated, regardless of their location or network environment. The model challenges the traditional notion of "trust but verify" by implementing strict access controls and continuous verification processes.

Zero Trust vs. Traditional Security: The Power of Automation and AI in Modern Cybersecurity

-

The Zero Trust Model has emerged as a powerful alternative to traditional security models in the ever-evolving cybersecurity landscape. It challenges the long-standing notion of Trust within a network and offers a more proactive, comprehensive approach to safeguarding sensitive data.  This article conducts a comparative analysis of Zero Trust and traditional security models, shedding light on what sets Zero Trust apart and why it is gaining momentum. Traditional Security: The Perimeter Defense Paradigm The idea of a network perimeter has long been a cornerstone of conventional security approaches. Trust is often assumed inside the network, while external entities are treated as potential threats. Critical characteristics of traditional security include: Firewalls and Intrusion Detection Systems (IDS) - They serve as a perimeter defense and stop unlawful entry. To identify insider risks, though, they might have trouble. VPN and Network Segmentation -   These technologies crea...
